CRITICAL FIXES: - Add directory restoration trap in maldet install (prevents PWD corruption) HIGH PRIORITY FIXES: - security-tools.sh: Make maldet detection consistent with other scanners - security-tools.sh: Improve ClamAV freshclam detection (add cPanel paths) - security-tools.sh: Add timeout protection to getenforce and aa-status - malware-scanner.sh: Integrate memory monitoring into ClamAV scan loop - malware-scanner.sh: Initialize memory_check_count for periodic checks SECURITY & RELIABILITY IMPROVEMENTS: - Prevents directory corruption in install functions - Better maldet detection across different installation paths - Timeout protection prevents script hangs on misconfigured systems - Periodic memory checks during long scans prevent OOM conditions All changes verified with syntax check. MALDET_ONLY flag already correctly implemented.
